Abstract: Cutting edge assemblies are normally utilized on the leading edge of implements to protect the leading edge of the implement from wear. In order to have a readily removable cutting edge assembly that can be replaced in the field, it is necessary to provide fastening means to retain the respective components to the implement. Since a surface and corresponding holes in the respective elements of the cutting edge assembly must be provided, the respective components are weakened and thus tend to break when used under high load conditions. In this subject arrangement, a cutting edge assembly is provided having a base edge with a scalloped leading edge. A plurality of teeth is provided and each tooth is releasably attached in space relation to the base edge. A plurality of base edge protectors is also provided and each protector is connected to the base edge between the respective teeth of the plurality of teeth.

Abstract: A locked connection for structures engageable with abrasive material and the like including a pair of relatively elongated elements at least one of which is subject to abrasive wear, the elements having parallel longitudinally extending centerlines and spaced apart generally planar surfaces arranged at an angle to the centerlines and between which a bi-stress lock is positioned.

Abstract: The invention is designed primarily for use with resilient tine components which include a pair of resilient spring coils having an attaching U extending between adjacent ends and a resilient tine extending from the outer end of each of the resilient coils substantially perpendicular to the longitudinal axis thereof.

The present invention overcomes these disadvantages by provided a sleeve which engages over the worn ends of the tines and is secured thereto and which has a replacement tine portion secured within the other end of the tubes and extending axially therefrom thus returning the tines to their original length. The sleeves can be secured to the worn ends of the tines either by welding, set screws or other means.
